Title: Film formation by local mocvd growth
Inventor: ITAGAKI TAKUSHI
IPC: C23C16/04
Filed: 1995-03-27
Abstract: PURPOSE: To provide a method for film formation based on local MOCVD growth wherein the degree of increase in growth rate for each constituting layer can be controlled during a batch local growth of a semiconductor optical waveguide structure and so on. CONSTITUTION: Slits 3 are formed to divide a mask 1. The growth self-stopping function of (111) B plane growth at the slits 3 and variation in effective mask width at growing time before and after that, are utilized to produce variation in the degree of increase in growth rate with a lapse of growing time. During the period from the start of growth to a time when the cross-sectional shape of growth becomes isosceles triangular at the slits 3 and the growth self-stops, growth seeds are consumed by the slits 3. Therefore, the degree of increase in growth rate is reduced to a value lower than that in the growth using a conventional mask. During this period a lower cladding layer is grown and its growth is completed.  After the self-stopping at the slits 3, a MQW waveguide layer and an upper cladding layer are grown at mask openings 2 at almost the same degree of increase in growth rate as a conventional mask having no slits is used.

Abstract: PURPOSE:To form an elliptical spot at a focus position of minimizing the number of apertures in a track direction with a shaping prism. CONSTITUTION:The diameter of a beam spot on a recording film is in proportion to a wavelength and in inverse proportion to the number of apertures N.A. In case of a semiconductor laser, the wavelength is limited, and therefore, the size of the spot is determined by N.A. Then, when the N.A. of the width to the height is made smaller, the spot is not shortened in the width direction and the elliptical spot is obtained. Here, when the N.A. in the track direction is shortened by using a shaping prism 4, the loss of a light quantity hardly occurs and a long elliptical spot 21 can be formed in the direction of a track 22.

Title: Treatment of resist
Inventor: ARAI TETSUHARU
IPC: H01L21/3065
Filed: 1987-03-24
Abstract: PURPOSE:To contrive the improvement of the heat resistance and plasma resistance of resist by a method wherein the initial heating temperature to the resist in a pressure reduced atmosphere is set at a temperature a little higher than the initial flow temperature of the resist and the resist is heated up at roughly the same speed as the rising speed of the flow temperature. CONSTITUTION:A semiconductor wafer 5 coated with resist 4 applied thereon is placed in advance on a wafer treating stand 6 heated a little higher than a flow temperature which is the heat-resistant temperature of the resist 4. At this time, the pressure in a treating chamber 7 is ready-reduced. Ultraviolet light-including light which is emitted from a high-pressure mercury-arc lamp 1 is irradiated on the resist 4. The flow temperature of the resist 4 is made to ride by this irradiation, but the heater power of the stand 6 is controlled to this and the temperature of the resists is always made to rise in a state that it is a little higher than the flow temperature. Thereby, the time to take for the treatment of the resists is significantly reduced to improve the treating capacity and even in case the resist films are thick, the heat resistance can be effectively improved up to their bottom parts.

Title: Method for estimating remaining amount of electrolyte of fuel battery
Inventor: WATANABE ATSUO
IPC: H01M8/04
Filed: 1984-04-05
Abstract: PURPOSE:To estimate remaining amount of electrolyte of matrix layer by supplying test gases to both electrode layers in different concentration and detecting an electromotive force generated by a fuel battery during such period. CONSTITUTION:As a gas which generates electro-chemical reaction with both electrode layers, there is a hydrogen gas, for example, in case the electrolyte is phosphoric acid. Those which reacts with any of the positive and negative electrodes and becomes anion or cation in the electrolyte may be used. When the test gases in different concentration are supplied to both electrode layers, an electromotive force is respectively generated in each electrode layer in accordance with the concentration of test gas and difference of such electromotive forces is generated as an electromotive force of a battery. When vacant holes in the porous matrix layer are not filled with electrolyte, the test gas flows, even in the least amount, toward low concentration side from high concentration side. As a result, difference between both electrode layers becomes small and an electromotive force of battery is lowered.
